The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package

Overview of assessment

A person who demonstrates competency in this unit must be able to remove and install the components of aircraft basic instrument systems while observing all relevant safety and component handling precautions

Critical aspects for assessment and evidence required to demonstrate competency in this unit

It is essential that cleanliness requirements and safety precautions applicable to the system being maintained are fully observed understood and complied with as well as work practices associated with electrostatic sensitive devices

Evidence of transferability of skills and knowledge related to removal and installation is essential This is to be demonstrated by application across a range of aircraft instrument system components as listed in the Range Statement An understanding of the attachment methods connection of hardware and the need for adjustment or calibration and system operation as they relate to the work must be demonstrated before undertaking any action

The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements of the Unit of Competency are being achieved under routine supervision on at least one component from each of Groups to as listed in the Range Statement This shall be established via the records in the Log of Industrial Experience and Achievement or where appropriate an equivalent Industry Evidence Guide

Context of and specific resources for assessment

Competency should be assessed in the workplace or simulated workplace using tools and equipment specified in maintenance manuals It is also expected that generalpurpose tools test and ground support equipment found in most routine situations would be used where appropriate

Method of assessment

Guidance information for assessment

Individuals being assessed who have already attained MEAA Maintain basic light aircraft instrument systems and components will have met all of the criteria for this unit Log of Industrial Experience and Achievement records relating to MEAA Maintain basic light aircraft instrument systems and components may be accepted as also meeting the evidence requirements for this unit

Individuals being assessed who have already attained MEA275A Maintain basic light aircraft instrument systems and components, will have met all of the criteria for this unit. Log of Industrial Experience and Achievement records relating to MEA275A Maintain basic light aircraft instrument systems and components, may be accepted as also meeting the evidence requirements for this unit.
